Eulg?

Nicolas: "Daddy is there something called Eulg?"
Me: "I don't know, what does Eulg do?"
Nicolas: "You know, it makes things break apart."
Me: "Makes things break apart?"
Nicolas: "It's the opposite of glue, which makes things stick together"
Me (with a giggle): "I don't know Nicolas but that is very funny, Eulg!!"

So is there? :)
